LHS = {tex}\frac { 1 + \sin \theta - \cos \theta } { 1 + \sin \theta + \cos \theta }{/tex}
= {tex}\frac { ( 1 - \cos \theta ) + \sin \theta } { ( 1 + \cos \theta ) + \sin \theta }{/tex} = {tex}\frac { 2 \sin ^ { 2 } \frac { \theta } { 2 } + 2 \sin \frac { \theta } { 2 } \cdot \cos \frac { \theta } { 2 } } { 2 \cos ^ { 2 } \frac { \theta } { 2 } + 2 \sin \frac { \theta } { 2 } \cdot \cos \frac { \theta } { 2 } }{/tex}
[{tex}\because{/tex} sin2x = {tex}\frac { 1 - \cos 2 x } { 2 } \Rightarrow{/tex} {tex}2 sin^2x = 1 - cos 2x{/tex} and {tex}2sin^2 \frac{x}{2} = 1 - cosx{/tex} and {tex}2 cos^2{/tex} {tex}\frac { x } { 2 }{/tex} {tex}= 1 + cosx{/tex} and {tex}sinx = 2sin{/tex} {tex}\frac { x } { 2 }{/tex} {tex}\times{/tex} {tex}cos{/tex} {tex}\frac { x } { 2 }{/tex}]
= {tex}\frac { \sin ^ { 2 } \frac { \theta } { 2 } + \sin \frac { \theta } { 2 } \cdot \cos \frac { \theta } { 2 } } { \cos ^ { 2 } \frac { \theta } { 2 } + \sin \frac { \theta } { 2 } \cdot \cos \frac { \theta } { 2 } } = \frac { \sin \frac { \theta } { 2 } \left[ \sin \frac { \theta } { 2 } + \cos \frac { \theta } { 2 } \right] } { \cos \frac { \theta } { 2 } \left[ \cos \frac { \theta } { 2 } + \sin \frac { \theta } { 2 } \right] }{/tex}
= {tex}\frac { \sin \frac { \theta } { 2 } } { \cos \frac { \theta } { 2 } }{/tex} = tan {tex}\frac { \theta } { 2 }{/tex} = RHS
{tex}\therefore{/tex} LHS = RHS
Hence proved.

Mechanics (Greek μηχανική) is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. It can also be defined as a branch of science which deals with the motion of and forces on objects.

Spermatogenesis is a concerted sequence of events during maturation of spermatogonia into spermatozoa. The process involves differential gene-expression and cell-cell interplay regulated by the key endocrine stimuli, i.e., follicle-stimulating hormone (FSH) and luteinizing hormone (LH)-stimulated testosterone. In women, this hormone stimulates the growth of ovarian follicles in the ovary before the release of an egg from one follicle at ovulation. It also increases oestradiol production. In men, follicle-stimulating hormone acts on the Sertoli cells of the testes to stimulate sperm production (spermatogenesis).
